CHARLES L. reien; JR., or rrrisisReH,' PENNSYLVANIA-' To all whom t may Concern:

Be it known that I, CHARLES L. PEIRGE, J r., a citizen of the United States, and a resident of Pittsburgh, in the county of Alleghenyv and State of Pennsylvania, have invented certain new and 'useful Improve-- mentsin Insulator-Supporting Brackets, of which the following is a specification. My invention relates to insulator supporting brackets particularly adaptable for supporting the conductors o f high tension distributing circuits.

Among the important objects of the invention are to provide a built-up bracket which can be inexpensively manufactured; to so brace the bracket thatv it will possess great strength and will efficiently meet any service strain in any direction; to provide suchv` form of bracket that a number thereof may be arranged in any .desired manner on l a pole or other support; to provide a bracket which isadjustable to fit the varying diameter of poles and which in any position of adjustment can be rigidly secured to the support; and to provide an all metal bracket which is treated to efficiently withstand the weather.

The various features of the invention will be fully understood by reference to the acor steel. The insulator receiving member 5 of the bracket shown is formed from a length of ordinary pipe bent in one direction at ci and in the opposite direction at b to off-set the upper end c from the lower end (l, this end cl being forged to form a widened base for engaging the support such as a'pole 29. The upper section e of the part c is preferably tapered by forging to receive .a suitable thimble t, the thimble shown being in the form of a wire helix, it being underst0od,of course, that other forms of thimbles may be used or that the end e may be i threaded or otherwise treated for directly receiving insulators.

The base d is shownsecured-to the pole insulina-SUPPORTING BRACKET.

may be used, and in order to hold the part 5 1n proper vertical 'alin'ement I provide .a

brace member 6 whose construction isbest shown in Fig. '3. The brace isjof general V-shape and preferably bent from a single length of stock metal such as channel bar,-

a loop or sleeve g being provided at the bend for receiving the upper part c of the bracket.

member 5. The ends L and i of the brace limbs are preferably curved to accurately fit the .curved surface of the pole and 'these' ends are each vprovided with a plurality f.bolt' 4holes j forreceiving lag bolts or'through bolts 7c. The sections of the limbs adjacent the loop' g are preferably secured together by a rivet or bolt m. This f'orm of brace is Very strong but sufficiently iiexible so that the limbs can be readily spread or brought together depending upon the4 diameter of the pole and to more snugly fit the pole.

The limbs of the brace receive a considerable portionof the pole, and the resulting bracket structure is therefore very rigidly trussed and braced to meet anyA service strain, even 'at sharp corners, the limbs of the brace preventing rotation of the bracket about .the pole. The parts of the bracket after formation are preferably hotV galvanized on all sides and thus fully protected against the weather.

The particular structure of the brackets allows them to be readily spaced in any desired manner on a pole. In Fig. l three brackets are shown, two on one side, and one on the opposite side of the pole, the insulator supporting ends ofthe brackets extending soI upwardly and being equidistant from each other, this being a desirable arrangementfor three Wire suspension. y

ln Fig. 2 is shown a somewhat modified structure and arrangement. The members 5 are of substantially the same shape as those of Fig. l except that the insulator supporting ends n are flattened by forging and provided with a hole o, insulators of the bell type beingr adapted for suspensionVV from these ends, which extend downwardly. The

brackets 6 are of the same shape and construction as those in Fig. Il and their loops g receive the members 5 'just above flattened ends 0.

The bracket structures may, of course, be arranged in'any other desired manner on a pole or other support and their supporting ends may be of shapes other than those to receive different styles and ccnl ons of insulators or insulator supvIorting attachments. I do not therefore delsire to be limited to the precise forms, structures and arrangements shown.

I claim as follows:

1. An insulator supporting bracket struc ture comprising a bracket memberv reversely bent and shaped at one end to form a supporting base and shaped at the rother end to receive an insulator or insulator support, and a V-shaped brace receiving the bracket member at its Abend and adapted at its ends to be secured against the opposite sides'of a support.

2. An insulatorsupporting bracket structure comprising a bracket member re; versely bent and having one end flattened to form a base adapted to be secured `directly -to a pole and at its other end being shaped to receive an insulator or insulator support, and a V-shaped brace having a loop at 1ts bend for receiving the bracket member, and

having its ends curved to ft the opposite rounded sides of the supporting pole, said ends being provided With` bolt holes by means of which they may be secured to the pole.

3. An insulator supporting bracket structure comprising a bracket part reversely bent and flattened at one end to form a base adapted to be secured directly7 to a pole and shaped at its other end to receive an insulator or insulator support, and a V-shaped brace member bent from a'single length ol" metal, said brace member being looped at its bend to receive the insulator supporting end of the bracket member and having its ends curved to fit the oppositesides of the pole, and said lator supporting end of the bracket member,

the lilnbs of the brace member being each provided with a plurality of bolt holes whereby such limbs may be secured to the opposite sides of a pole.

5. An insulator supporting bracket structure comprising ay bracket member in the form of a length of pipe reversely bent and having one end flattened to form a base vface.

6. An insulator supporting bracket structurecomprising a bracket member adapted y to be secured at one end to a pole and Shaped at its other end to receive an insulator or insulator support, and a V-shaped brace member adapted to receive the bracket mem# ber at its bend and having its ends provided with bolt holes whereby they may be secured to opposite sides of a pole, such brace being flexible whereby the ends may be spread apart or brought together in accordance with the diameter of the pole.

7 An insulator supporting bracket structure comprising a bracket member having one end adapted to be secured to a pole and its other end shaped to receive an insulator or insulator support, and a V-shaped brace member bent from a single length of metal, said brace member being looped at itsbend and the lsides thereof secured together to keep the loop closed, said sides being llexible whereby they may be adjusted to lit snugly against the sides of a pole and their ends having bolt holes for receiving bolts by means of which they may be secured to a pole.

8. An insulator supporting bracket structure 'comprising a bracket member having one endadapted to be secured toa pole and its other end shaped to receive an insulator or insulator support, and a V-shaped brace member bent from a single length of metal, said brace member being looped at its bend and the sides thereof secured together to keep the loop closed, said sides being flexible whereby they may be adjusted to lit snugly against the sides of a pole and their ends having bolt holes for receiving bolts by means of which they may be secured to a pole, said ends being rounded to moreaccurately lit the pole.

In witness whereof, I hereunto subscribe my name this 27 day of April, A. D., 1914.
